Answer:

1) Mean 2) Mean 3) Spread

Step-by-step explanation:

In the Normal Distribution (Bell Shaped) the Mean, Mode, and Median coincide and they are the longest axis in the middle of the curve. Therefore the Mean is the center of the Distribution, and the Standard Deviation and other Measures of Spread (Standard Deviation, Variance) show us how the data vary, i.e. the variability of the data collected.
